Yes those would probally help..

Or perhpaps just confuse things more.  9's in XMAP2 is PCI accessable,
No Cache, No Write, Read.

I'm not sure how you would load the shadow copy of the bios into this
range with write disabled .  Until we started setting the write bit
for these ranges the emulator was getting all 0xFFs for its data.

Dosen't look like it.  Is that a big problem?  I know for the gx2 it's
a big issue since it dosen't have PCI config space without it.  But
this part seems to have PCI config method #1 without SMM.
